Description

Modular automatic counting optical fiber winder and use method thereof

Technical Field

The application relates to a modular automatic counting optical fiber winder.

Background

Optical fibers, also known as optical fibers, are a type of fiber made of glass or plastic, and are light-conducting tools that use the principle of total internal reflection or the like to transmit light through these fibers. One of the most important advantages of modern optical fibers is its flexibility. Since the optical fiber is to be installed in different situations, the optical fiber must be capable of being bent. When an optical fiber bends, the confinement mechanism within its waveguide is disturbed, causing a portion of the light to escape from the waveguide mode into a leaky mode or even into a radiative mode, thereby causing bending losses. Bending loss is one of the loss characteristics of an optical fiber. Bending losses can be classified into macrobending losses and microbending losses according to the degree of bending of the optical fiber.

When the bending loss of an optical fiber is measured in an experiment, the optical fiber exhibits different transmission loss characteristics at different bending radii. In the normal experimental process, an experimenter cannot wind the optical fiber according to the same bending radius well, and meanwhile, the length of the optical fiber cannot be accurately measured, so that the experimental result of the bending transmission loss characteristic of the optical fiber has a certain error. When the simple optical fiber winder commonly used in the market is used for winding optical fibers in experiments, the winding radius of the winder cannot be adjusted according to the characteristics and experimental requirements of different types of optical fibers, and meanwhile the problems that the winding of the optical fibers is uneven, the length of the optical fibers is difficult to measure and the like exist. Because of the fragile nature of the optical fiber, improper fiber optic spoolers are prone to damage to the optical fiber. Fiber optic spoolers of different spooling radii are therefore required for experiments with different types of optical fibers.

Development of the optical fiber winder based on the operation convenience, the functional diversity and the combination expansibility is more needed by experiments and expected by industries, and development of the modular automatic counting optical fiber winder is urgent.
